Use the power rule
d(x^n)/dx = n·x^(n-1)
to form the derivative.
f'(x) = 4·2x -4
f'(x) = 8x - 4
Now, substitute "a" for "x" to find f'(a):
f'(a) = 8a - 4
Answer:
Simplified version: 10x^5 - 1x^4 + 2x^3 - 6
Step-by-step explanation:
Since your birthday is 10/1/2006 we can use 1012006 as our digits.
We can make a random polynomial: 10x^5 - 1x^4 + 2x^3 + 0 x^2 + 0x - 6
(since 0 are meaningless we can simply this further into the below equation)
10x^5 - 1x^4 + 2x^3 - 6
Here's an example: https://www.wyzant.com/resources/answers/730225/birthday-polynomial-project-for-04-15-2004
6 x minus 4 and start fraction 9 over 10
Cost = fix cost + hourly cost - discount
Cost = 4* [5 + 4x - 4x(20/100)] = 4*[5 + 4x - 0.8x] = 4*[5 + 3.2x] = 20 + 12.8x
Answer: option B) 12.8x + 20
The answer is 4.5 miles. Hope it helps!
